Age-specific differences in treatment and survival of patients with cervical cancer in the southeast of The Netherlands, 1986-1996

HPV-Vaccine Hesitancy in Colombia: A Mixed-Methods Study

In Colombia, the uptake rate of the HPV vaccine dropped from 96.7% after its introduction in 2013 to 9% in 2020. To identify the behavioural components of HPV-vaccine hesitancy in females aged 15 and under and their families, we conducted a convergent mixed-methods study in which 196 parents/caregivers responded to an online questionnaire and 10 focus groups were held with 13 of these parents/caregivers, and 50 age-eligible girls. The study is novel as it is the first to explore the factors influencing HPV-vaccine hesitancy alongside the COVID vaccine within an integrative model of behaviour change, the capability-opportunity-motivation-behaviour (COM-B) model. We found that COVID-19 has had an impact on the awareness of HPV and HPV vaccination. Lack of information about the vaccination programs, concerns about vaccine safety and the relationship between HPV and sexuality could be related to vaccine hesitancy. Trust in medical recommendations and campaigns focused on the idea that vaccination is a way of protecting daughters from cervical cancer could improve HPV vaccine uptake.

Clinicopathological Features and Survival of Adolescent and Young Adults with Cervical Cancer

PURPOSE

To explore clinicopathological characteristics and their prognostic value among young patients with cervical cancer (who are aged ≤25 years old).

METHODS

The Surveillance, Epidemiology, and End Results Program (SEER) database was used to extract data on cervical cancer patients. They were then stratified by age as young women (≤25 years old) and old women (26-35 years old) and analyzed for clinicopathology characteristics and treatment modalities. Prognosis was analyzed using Kaplan-Meier survival curve, as well as hazard ratios using Cox regression modeling. The nomogram was developed based on Cox hazards regression model.

RESULTS

Compared to 26-35 years old women, patients aged ≤25 years tended to be white ethnicity, unmarried, had earlier stage of disease. There was also a better prognosis among younger cohort. Grade, FIGO stage, histologic subtypes, and surgical modalities influenced the survival outcomes of young patients. Among young cohorts, surgery prolonged the survival time of IA-IIA stage patients while surgical and non-surgical management presented no statistically prognostic difference among patients at IIB-IVB stage. Besides, the nomogram which constructed according to Cox hazards regression model which contained independent prognosis factors including FIGO stage, surgery type, and histologic type of tumor can robustly predict survival of young patients.

CONCLUSION

Cervical cancer patients ≤25 years old were uncommon and lived longer than the older patients. Among these young patients at IA-IIA stage, surgical treatment could be more effective at preventing death than non-surgery. The nomogram could perfectly predict the prognosis of young adults and adolescents with cervical cancer.

Influence of age on treatment and prognosis of invasive cervical cancer

OBJECTIVE

Invasive cervical cancer is considered a young women's disease, however up to 20 % of cases develop cervical cancer at advanced ages. The aim was to characterize invasive cervical cancer in women aged 65 and older assessing age-specific survival differences.

STUDY DESIGN

A retrospective study including cervical cancer patients was conducted at Hospital del Mar Barcelona from July-2007 to December-2016. Women were stratified: <65 or ≥65years. Clinical and pathological data were collected. Multivariate analysis was used to compare outcomes. Adjusted hazard ratios with 95 % confidence intervals for disease-free survival, and overall survival were estimated using Cox proportional hazards models.

RESULTS

124 patients with invasive cervical cancer (n = 87 < 65years and n = 37 ≥ 65years) were included. At diagnosis, 48.3 % of <65years patients were diagnosed at advanced stages, while 64.9 % in ≥65years (p = 0.018). Standard treatment was given to 83.9 % of patients in <65years group compared to 62.2 % in ≥65years (p = 0.015). Disease-free survival and overall survival showed no significant differences between groups. Age ≥65 did not predict worse disease-free survival (HR: 0.3 95 %CI, 0.04-3.1, p = 0.347) or overall survival (HR: 0.82 95 %CI, 0.3-2.3, p = 0.729).

CONCLUSION

Invasive cervical cancer was diagnosed at advanced stages and was treated less frequently with radical intention in patients ≥65years; overall survival and disease-free survival were similar to those cervical cancer diagnosed at younger ages.

Cervical Cancer in Young Women: Do They Have a Worse Prognosis? A Retrospective Cohort Analysis in a Population of Mexico

BACKGROUND

Cervical cancer (CC) is a global problem; it is among the five leading causes of cancer death in women. Several studies have examined the association between age and disease prognosis; however, controversy still exists. The objective of the present study is to determine if age at diagnosis has an impact on overall survival (OS) and disease-free survival (DFS).

MATERIALS AND METHODS

Retrospective cohort of 2,982 patients with CC treated at the National Cancer Institute of Mexico from 2005 to 2015. We collected demographic, clinical, and treatment data, as well as current status, of 2 groups: women under and over 40 years of age. We calculated OS and DFS rates with Kaplan-Meier estimates. Cox proportional hazards modeling was used to determine risks.

RESULTS

The median follow-up time was 26.5 months (percentile [P]₂₅ -P₇₅ , 11-60.23). When comparing DFS, OS, stage, and histologic subtype between young patients <40 and adult patients >40, we did not observe any difference. We found that in both groups, locally advanced and advanced stage, neuroendocrine subtype, hydronephrosis, and positive inguinal lymph nodes increased the risks of death and recurrence. Having been pregnant was identified as protective factor in DFS (hazard ratio, 0.54; 95% confidence interval, 0.04-0.71).

CONCLUSION

We corroborated that age at diagnosis is not a prognostic factor for decreased or increased OS or DFS, and in both groups, the stage, histologic subtype, hydronephrosis, and node involvement were identified as factors adverse to OS and DFS, and pregnancy history was a protective factor in DFS.

IMPLICATIONS FOR PRACTICE

The present study directly affects everyday clinical practice because it allows us to focus on the most relevant prognostic factors in patients with cervical cancer. When planning treatment and follow-up, clinicians should focus on stage at diagnosis, histologic subtype, hydronephrosis, and distant metastasis instead of patients' age. They should also be aware of any previous pregnancies and poor response, or nonresponse, to treatment, which results in disease progression and persistence. Paying attention to these factors affecting overall survival and disease-free survival will help treat patients better and increase their chances of survival and improve their quality of life.

Management of elderly women with cervical cancer

BACKGROUND

Elderly women with cervical cancer receive less therapy in comparison with their younger counterparts. The exact reason(s) for this treatment strategy remains unclear.

PATIENTS AND METHODS

We performed a multicenter, retrospective registry-based study of 1559 patients with cervical cancer. The primary outcome was the reason for not performing the indicated treatment.

RESULTS

Median follow-up was 67.8 months. A total of 956 women were eligible for analysis: 693 (64.2%) were younger than 60 years and 387 (35.8%) were aged 61 years old and older. Elderly women were more likely to have undifferentiated cervical cancer at an advanced stage. For early stage (stage IA1-IIA), tumors patients 61 years old and older were less likely to receive surgery [odds ratio (OR) 0.39; 95% CI 0.20-0.77] and radiochemotherapy (OR 0.37; 95% CI 0.21-0.66) compared with the group of patients aged < 60 years. The rate of lymphadenectomy was similar in both age groups. Patients 61 years old and older with advanced stage (IIB-IV) cervical cancer were also less likely to receive surgery [odds ratio (OR) 0.42; 95% CI 0.27-0.66], lymphadenectomy (OR 0.30; 95% CI 0.12-0.51) and radiochemotherapy (OR 0.31; 95% CI 0.20-0.48) compared with patients aged < 60 years. Notably, the rate of indicated but not performed therapies proportionally increased with an increase in patient age and the most important reason for this phenomenon was the failing of recommendation.

CONCLUSIONS

Elderly women with cervical cancer are undertreated and this is more likely because the therapy was not recommended.

Definitive chemoradiotherapy for advanced cervical cancer: should it be different in the elderly?

BACKGROUND

Cervical cancer (CC) is the second most common cancer in Brazilian women, and approximately 10% of cases occur in elderly patients (pts). In this age group, disease is usually diagnosed in more advanced stages and oncological therapies are usually less intensive, due to comorbidities and impaired performance status.

METHODS

Retrospective analysis of pts ≥65 years old with CC admitted at a Brazilian University Cancer Center from August 2008 to February 2012. We performed a descriptive analysis of baseline performance status (PS), disease stage (FIGO), histology, body mass index (BMI), treatment received and overall survival, using the Kaplan-Meier method.

RESULTS

900 medical records were analyzed and 75 pts (8%) fulfilled the inclusion criteria. Median age was 73.4 years old (±5.5 years). Squamous cell carcinoma (SCC) was the most common histology (71 pts, 94.7%). 67 (89.3%) had PS 0 or 1 and 52 pts (69.3%) were eutrophic (BMI 18.5-25 kg/m(2)). At presentation, disease staging consisted of 18 pts (24%) stage I, 35 pts (46.7%) stage II, 8 pts (10.7%) stage III, 12 pts (16%) stage IVa and 2 pts (2.7%) stage IVb. 24 pts (32%) underwent surgery (hysterectomy, adnexectomy, pelvic and paraaortic lymphadenectomy). Adjuvant treatment with radiotherapy (RT) was performed in 13 pts (total dose of external RT in pelvis ranged from 39.6 to 45 Gy, parametrial boost ranged from 14 to 20 Gy and 4 inserts from 7 to 7.5 Gy of brachytherapy); 8 of them received concomitant platinum-based chemotherapy (CT). 30 pts underwent definitive CRT, 17 definitive RT, 1 palliative CT and 3 best supportive care. In the CRT group, 18 pts received cisplatin (CDDP 40 mg/m(2)/w/6w) and 12 carboplatin (AUC 2/w/6w). During definitive CRT, treatment was discontinued in 39% of pts who received CDDP and 25% of pts who received carboplatin, all due to treatment toxicities. CDDP was associated with more nefrotoxicity (5 pts, 28%) than carboplatin (1 pt, 8.3%). The CDDP group also presented more radiodermatitis and stroke. However, myelosuppression and diarrhea were similar in both groups. After a 26.1-month follow-up, median OS was not reached.

CONCLUSIONS

Despite advanced age, more than 60% of pts underwent complete CRT treatment. Thus, age should not be the only factor to guide therapeutic decisions in CC. Carboplatin was better tolerated than CDDP in CRT group, but prospective trials are necessary to evaluate the best treatment option in this population.

The cost of anal cancer in England: retrospective hospital data analysis and Markov model

BACKGROUND

Anal cancer requires a multidisciplinary approach to treatment with often complex interventions. Little is known regarding the associated costs and resource use.

METHODS

Patient records were extracted from a national hospital database to estimate the number of patients treated for anal cancer in England. Identified resource use was linked to published UK cost estimates to quantify the reimbursement of treatment through the Payment by Results system. A mathematical model was developed simultaneously to validate findings and to calculate the average 10-year cost of treating a squamous cell anal carcinoma case from diagnosis. The model utilised data from the Association of Coloproctology of Great Britain and Ireland's anal cancer position statement.

RESULTS

On average, 1,564 patients were admitted to hospital and 389 attended an outpatient facility per year. The average annual cost per inpatient and outpatient ranged from £4,562-£5,230 and £1,146-£1,335, respectively. Based on the model estimates, the inflated cost per case was between £16,470-£16,652. Results were most sensitive to the mode of admission for primary treatment and the costs of staging/diagnosis (inflated range: £14,309-£23,264).

CONCLUSIONS

Despite limitations in the available data, these results indicate that the cost of treating anal cancer is significant. Further observational work is required in order to verify these findings.

Changes in prevalence and clinical characteristics of cervical cancer in the People's Republic of China: a study of 10,012 cases from a nationwide working group

PURPOSE

About one-third of the world's total annual new cervical cancer cases are found in the People's Republic of China. We investigate the prevalence and clinical characteristics of cervical cancer cases in the People's Republic of China over the past decade.

METHOD

A total of 10,012 hospitalized patients with cervical cancer from regions nationwide were enrolled from 2000 to 2009. Demographic and clinical characteristics, therapeutic strategies, and outcomes were analyzed.

RESULTS

The mean age at diagnosis of all cervical cancer patients was 44.7 ± 9.5 years, which is 5-10 years younger than mean ages reported before 2000 in the People's Republic of China. The age distribution showed 16.0% of patients were ≤35 years old, 41.7% were 35-45 years old, and 41.7% were >45 years old. Early stage diagnoses were most prevalent: 57.3% were stage I, 33.9% were stage II, and 4.3% were stage III or IV. Most patients (83.9%) were treated with surgery, and only 9.5% had radiotherapy alone. Among 8,405 patients treated with surgery, 68.6% received adjuvant treatments, including chemotherapy (20.9%), radiotherapy (26.0%), and chemoradiotherapy (21.9%). Among stage IA patients, 16.0% were treated with corpus uteri preservation. The proportion of ovarian preservation was 42.0%.

CONCLUSIONS

Cervical cancer cases in the People's Republic of China show increasing prevalence in young patients and at early stages. In the past 10 years, surgery has become the dominant treatment and is increasingly combined with adjuvant chemotherapy for patients with stages I and II. Conservative surgical approaches are reasonable options for genital organ preservation in selected patients.

Comparing bivalent and quadrivalent human papillomavirus vaccines: economic evaluation based on transmission model

OBJECTIVES

To compare the effect and cost effectiveness of bivalent and quadrivalent human papillomavirus (HPV) vaccination, taking into account differences in licensure indications, protection against non-vaccine type disease, protection against disease related to HPV types 6 and 11, and reported long term immunogenicity.

DESIGN

A model of HPV transmission and disease previously used to inform UK vaccination policy, updated with recent evidence and expanded to include scenarios where the two vaccines differ in duration of protection, cross protection, and end points prevented.

SETTING

United Kingdom. Population Males and females aged 12-75 years.

MAIN OUTCOME MEASURE

Incremental cost effectiveness ratios for both vaccines and additional cost per dose for the quadrivalent vaccine to be equally cost effective as the bivalent vaccine.

RESULTS

The bivalent vaccine needs to be cheaper than the quadrivalent vaccine to be equally cost effective, mainly because of its lack of protection against anogenital warts. The price difference per dose ranges from a median of £19 (interquartile range £12-£27) to £35 (£27-£44) across scenarios about vaccine duration, cross protection, and end points prevented (assuming one quality adjusted life year (QALY) is valued at £30,000 and both vaccines can prevent all types of HPV related cancers).

CONCLUSIONS

The quadrivalent vaccine may have an advantage over the bivalent vaccine in reducing healthcare costs and QALYs lost. The bivalent vaccine may have an advantage in preventing death due to cancer. However, considerable uncertainty remains about the differential benefit of the two vaccines.

The human papillomavirus (HPV) vaccine and cervical cancer: uptake and next steps

Infection with a high-risk type of the human papillomavirus (HPV) is a major contributing factor in the vast majority of cervical cancers. Dissemination of the HPV vaccine is critical in reducing the risk of the disease. This descriptive review of HPV vaccine uptake in papers published between 2006 and 2011 focuses on studies conducted in girls and young women. In the United States, rates of immunization as per the protocol for teens (age 13-17 years) range from 6% to 75% and those for young women (age 18-26 years) range from 4% to 79%, although the samples and data collection methods vary. The epidemiology of HPV, the mechanisms of action, protocols for vaccine immunization, rates of uptake, and barriers to vaccination at the policy, provider, and patient levels are reviewed. Various intervention techniques are described, and policy-level programs, such as legislation supporting mandates, subsidized public education, and cost-reduction initiatives, are also explored. Increased distribution of the HPV vaccine in school-based clinics, evidencebased scripts for provider counseling of young patients and their parents, concurrent immunizations to adolescents, prevention visits, greater patient education and outreach, and the dissemination of academic detailing can help to boost vaccine uptake, particularly in underresourced communities. Population-based surveillance is necessary for robust estimates of uptake over time. Additional research is needed to comprehensively examine socio-demographic, psychosocial, and sociocultural factors that predict vaccine uptake according to the protocol. Increased study of the vaccine's long-term effectiveness, in both males and females and among extended age groups, is warranted.

Radiotherapy for Japanese elderly patients with cervical cancer: preliminary survival outcomes and evaluation of treatment-related toxicity

Purpose

To examine the preliminary survival outcomes and treatment-related toxicity for elderly patients with cervical cancer treated with radiotherapy (RT).

Methods

Forty patients ≥75 years old with cervical cancer who were treated with RT were evaluated. Of these 40 patients, 25 were classified as FIGO stage I or II and 15 as stage III or IVA. Thirty-five patients were treated with radical RT (RRT), and five were treated with surgery plus adjuvant RT (S + ART). External beam radiotherapy combined with high-dose-rate intracavitary brachytherapy was performed on 31 patients who were treated with RRT and on 2 patients who were treated with S + ART because of positive vaginal surgical margins. The patients’ median age was 78 years (range 75–89 years). Concurrent chemotherapy (CCT) was performed on five patients (RRT: 3, S + ART: 2).

Results

The median follow-up period was 20 months (range 1–85 months). Only one patient could not complete RT. The 3-year overall and disease-specific survival (OS and DSS) rates for all patients were 58 and 80%, respectively. Five patients experienced Grade 3 acute toxicity; two were treated with RRT (2/35), and three were treated with S + ART (3/5, 2 of them with CCT). Two patients experienced Grade 3 late toxicity; one was treated with RRT (1/35, with CCT) and the other was treated with S + ART (1/5). No Grade 4 or higher toxicity was experienced.

Conclusions

RRT for elderly patients with cervical cancer is generally effective and safe, but severe toxicity may occur with more aggressive treatment modalities.

Primary therapy for early-stage cervical cancer: radical hysterectomy vs radiation

OBJECTIVE

We compared survival for women with early-stage cervical cancer who were treated with primary radiation or radical hysterectomy.

STUDY DESIGN

Patients in the Surveillance, Epidemiology, and End Results database with stage IB1-IIA cervical cancer were examined. Radical hysterectomy was compared with primary combination external-beam and brachytherapy radiation.

RESULTS

A total of 4885 patients were identified. Multivariate analysis showed that radical hysterectomy was associated with a 59% reduction in mortality rate (hazard ratio, 0.41; 95% confidence interval [CI], 0.35-0.50). After stratification by tumor size, hysterectomy was associated with a 62% reduction in mortality rate (hazard ratio, 0.38; 95% CI, 0.30-0.48) for tumors that were <4 cm in diameter and a 49% improvement in survival (hazard ratio, 0.51; 95% CI, 0.36-0.72) for tumors that were 4-6 cm in diameter. Among women with tumors that were >6 cm in size, survival was equivalent between radical hysterectomy and radiation.

CONCLUSION

Our data indicate that, in women with cervical cancer lesions of <6 cm, radical hysterectomy is superior to primary radiation.

Incidence of cervical cancer after several negative smear results by age 50: prospective observational study

OBJECTIVE

To determine the incidence of cervical cancer after several negative cervical smear tests at different ages.

DESIGN

Prospective observational study of incidence of cervical cancer after the third consecutive negative result based on individual level data in a national registry of histopathology and cytopathology (PALGA).

SETTING

Netherlands, national data. Population 218,847 women aged 45-54 and 445,382 aged 30-44 at the time of the third negative smear test.

MAIN OUTCOME MEASURES

10 year cumulative incidence of interval cervical cancer.

RESULTS

105 women developed cervical cancer within 2 595,964 woman years at risk after the third negative result at age 30-44 and 42 within 1,278,532 woman years at risk after age 45-54. During follow-up, both age groups had similar levels of screening. After 10 years of follow-up, the cumulative incidence rate of cervical cancer was similar: 41/100,000 (95% confidence interval 33 to 51) in the younger group and 36/100,000 (24 to 52) in the older group (P=0.48). The cumulative incidence rate of cervical intraepithelial neoplasia grade I+ was twice as high in the younger than in the older group (P<0.001).

CONCLUSIONS

The risk for cervical cancer after several negative smear results by age 50 is similar to the risk at younger ages. Even after several negative smear results, age is not a good discriminative factor for early cessation of cervical cancer screening.

Estimating the Long-Term Clinical Impact of Cervical Cancer Vaccination in Taiwan

The high burden of human papillomavirus (HPV) infection and subsequent cervical cancer in the presence of screening in Taiwan suggests the need for further prevention strategies. Epidemiology and screening practices vary considerably between countries, and specific analyses are required to estimate the impact of HPV vaccination. This study adapted a computer-based health economic model to Taiwan to project the clinical impact of the introduction of a prophylactic vaccine against persistent HPV 16/18 infection on cervical disease. A Markov model based on the natural history of HPV and cervical cancer was developed to simulate transitions between health states (normal, HPV, cervical intraepithelial neoplasia [CIN] stages I to III, cervical cancer stages I to IV, and death) in the presence of screening. The model was calibrated to Taiwan epidemiological end points including age-specific HPV prevalence, prevalence of CIN lesions, and predicted cervical cancer incidence and mortality. Taiwanese screening and treatment practices were modeled, and published clinical trial data were used to estimate vaccine efficacy. With 100% vaccine coverage in a 13-year-old cohort of females, there is estimated to be a 71% reduction in cervical cancer cases and deaths due to all HPV types and substantial reductions in the prevalence of precancerous lesions and screening outcomes. Removing the risk of HPV infection of a large proportion of Taiwanese females, with a high underlying cervical cancer incidence rate, would be expected to have dramatic effects on the health care system and mortality in Taiwan.

Ethnic Disparities in Cervical Cancer Survival Among Medicare Eligible Women in a Multiethnic Population

Objectives:

To determine predictors of cervical cancer survival by socioeconomic status (SES), urbanization, race/ethnicity, comorbid conditions, and treatment among elderly Medicare-eligible women whose conditions were diagnosed with cervical cancer in a multiethnic population.

Methods:

A total of 538 women with cervical cancer aged 65 years or older were identified from 1999 to 2001 from the Texas Cancer Registry and were linked with the state Medicare data and Texas Vital Records to determine survival times. All women had similar access to care through Medicare fee-for-services insurance. A composite measure of SES was created using census tract-level data as was urbanization. Treatment and comorbid conditions were available from the Medicare data. Cox proportional hazards modeling was used for all-cause and cervical cancer-specific survival analysis.

Results:

Increased age (P < 0.0001) and advanced tumor stage (P < 0.0001) were associated with poorer all-cause and cervical cancer-specific survival. Having a comorbid condition was associated with all-cause survival (P < 0.01) but not cervical cancer-specific mortality. After adjusting for confounders, women receiving some form of treatment were almost half as likely to die with cervical cancer (adjusted hazard ratio = 0.68; 95% confidence interval, 0.52-0.89). After adjustment for all confounders, Hispanic women consistently had lower all-cause and cervical cancer-specific mortality rates relative to non-Hispanic white and non-Hispanic black women.

Conclusions:

Among women with similar health care coverage, Hispanic women had consistently lower all-cause and cervical cancer-specific mortality rates than other older women whose conditions were diagnosed with this disease in Texas. The presence of comorbid conditions and treatment were important predictors of survival, yet these factors do not explain the survival advantage for Hispanic women.

Health-related quality of life in cervical cancer survivors: a population-based survey

PURPOSE

In a population-based sample of cervical cancer survivors, health-related quality of life (HRQoL) was assessed 2-10 years postdiagnosis.

METHODS AND MATERIALS

All patients given a diagnosis of cervical cancer in 1995-2003 in the Eindhoven region, The Netherlands, and alive after Jan 2006 were identified through the cancer registry. Generic HRQoL (36-Item Short-Form Health Survey, EQ-5D), cervical cancer-specific HRQoL (European Organization for Research and Treatment of Cancer Quality-of-Life questionnaire cervical cancer module), and anxiety (6-item State Trait Anxiety Inventory) were assessed and compared with a reference population (n = 349). Data for tumor characteristics at diagnosis and disease progression were available.

RESULTS

A total of 291 women responded (69%), with a mean age of 53 +/- 13 (SD) years (range, 31-88 years). Treatment had consisted of surgery (n = 195) or a combination of therapies (n = 75); one woman had not been treated. Of all women, 85% were clinically disease free, 2% had a recurrence/metastasis, and in 13%, this was unknown. After controlling for background characteristics (age, education, job and marital status, having children, and country of birth), generic HRQoL scale scores were similar to the reference population, except for worse mental health in survivors. The most frequent symptoms were crampy pain in the abdomen or belly (17%), urinary leakage (15%), menopausal symptoms (18%), and problems with sexual activity. Compared with the 6-10-year survivors, more sexual worry and worse body image were reported by the 2-5-year survivors. Compared with surgery only, especially primary radiotherapy was associated with an increased frequency of treatment-related side effects, also after controlling for age and disease stage at diagnosis and follow-up.

CONCLUSIONS

Most cervical cancer survivors were coping well, although their mental health was worse than in the reference population. Even after 2-10 years, radiotherapy was associated with an increased frequency of treatment-related side effects.

Economic evaluation of human papillomavirus vaccination in the United Kingdom

OBJECTIVE

To assess the cost effectiveness of routine vaccination of 12 year old schoolgirls against human papillomavirus infection in the United Kingdom.

DESIGN

Economic evaluation.

SETTING

UK. Population Schoolgirls aged 12 or older.

MAIN OUTCOME MEASURES

Costs, quality adjusted life years (QALYs), and incremental cost effectiveness ratios for a range of vaccination options.

RESULTS

Vaccinating 12 year old schoolgirls with a quadrivalent vaccine at 80% coverage is likely to be cost effective at a willingness to pay threshold of pound30,000 (euro37,700; $59,163) per QALY gained, if the average duration of protection from the vaccine is more than 10 years. Implementing a catch-up campaign of girls up to age 18 is likely to be cost effective. Vaccination of boys is unlikely to be cost effective. A bivalent vaccine with the same efficacy against human papillomavirus types 16 and 18 costing pound13- pound21 less per dose (depending on the duration of vaccine protection) may be as cost effective as the quadrivalent vaccine although less effective as it does not prevent anogenital warts.

CONCLUSIONS

Routine vaccination of 12 year old schoolgirls combined with an initial catch-up campaign up to age 18 is likely to be cost effective in the UK. The results are robust to uncertainty in many parameters and processes. A key influential variable is the duration of vaccine protection.

Exploring older women's approaches to cervical cancer screening

The purpose of this qualitative study (N = 98, 11 focus groups) is to investigate how low-income, African American and Hispanic older women make decisions about cervical cancer screening. Using the health belief model to guide content analysis of transcripts, we found that primary barriers to screening were; embarrassment with, fear of, and pain from the test, difficulty in accessing screening, stigma associated with Medicaid coverage, and prior negative experiences with cancer detection. Women experienced cues to screening from their own bodies, in symptoms, and relied on spiritual beliefs to support them in coping with their health problems. Enhanced understanding of these factors could increase uptake of cervical cancer screening among the unscreened and underscreened.

Older female cancer patients: importance, causes, and consequences of undertreatment

Despite increased interest in treatment of senior cancer patients, older patients are much too often undertreated. This review aims to present data on treatment practices of older women with breast and gynecologic cancers and on the consequences of undertreatment on patient outcome. We also discuss the reasons and validity of suboptimal care in older patients. Numerous studies have reported suboptimal treatment in older breast and gynecologic cancer patients. Undertreatment displays multiple aspects: from lowered doses of adjuvant chemotherapy to total therapeutic abstention. Undertreatment also concerns palliative care, treatment of pain, and reconstruction. Only few studies have evaluated the consequences of nonstandard approaches on cancer-specific mortality, taking into account other prognostic factors and comorbidities. These studies clearly showed that undertreatment increased disease-specific mortality for breast and ovarian cancers. For other gynecological cancers, data were insufficient to draw conclusions. Objective reasons at the origin of undertreatment were, notably, higher prevalence of comorbidity, lowered life expectancy, absence of data on treatment efficacy in clinical trials, and increased adverse effects of treatment. More subjective reasons were putative lowered benefits of treatment, less aggressive cancers, social marginalization, and physician's beliefs. Undertreatment in older cancer patients is a well-documented phenomenon responsible for preventable cancer deaths. Treatments are still influenced by unclear standards and have to be adapted to the older patient's general health status, but should also offer the best chance of cure.

Estimating the long-term impact of a prophylactic human papillomavirus 16/18 vaccine on the burden of cervical cancer in the UK

To predict the public health impact on cervical disease by introducing human papillomavirus (HPV) vaccination in the United Kingdom, we developed a mathematical model that can be used to reflect the impact of vaccination in different countries with existing screening programmes. Its use is discussed in the context of the United Kingdom. The model was calibrated with published data. The impact of vaccination on cervical cancer and deaths, precancerous lesions and screening outcomes were estimated for a vaccinated cohort of 12-year-old girls, among which it is estimated that there would be a reduction of 66% in the prevalence of high-grade precancerous lesions and a 76% reduction in cervical cancer deaths. Estimates for various other measures of the population effects of vaccination are also presented. We concluded that it is feasible to forecast the potential effects of HPV vaccination in the context of an existing national screening programme. Results suggest a sizable reduction in the incidence of cervical cancer and related deaths. Areas for future research include investigation of the beneficial effects of HPV vaccination on infection transmission and epidemic dynamics, as well as HPV-related neoplasms in other sites.

Variation in the treatment of cervical cancer patients and the effect of consultant workload on survival: A population-based study

This population-based study aimed to investigate the extent of variation in the treatment of patients diagnosed with cervical cancer between 1995 and 2000, and the relationship between workload and survival, looking at managing consultants and clinical oncologists. Cases were identified from the Northern and Yorkshire Cancer Registry (n=1500) and divided into three groups according to their gynaecologists' or clinical oncologists' annual cervical cancer workload; 'low' (1-3 new patients), 'intermediate' (4-11 new patients) and 'high' (12+new patients). Over the study period, there was a decrease in the proportion of patients treated by low workload gynaecologists. After adjustment for age, stage and socioeconomic status, higher gynaecologist workload was associated with improved survival but this was not statistically significant. No such trend was found for clinical oncologist workload. During the 1990s, there were moves to establish more specialised care of gynaecological cancers, with referral to multidisciplinary teams. The trends observed in this study are consistent with the goals of policy.

Socioeconomic status and cervical cancer survival among older women: findings from the SEER-Medicare linked data cohorts

OBJECTIVES

Tumor stage, age, and cell type are well-characterized predictors for cervical cancer survival; socioeconomic factors may also play an important role. The purpose of this study is to estimate cervical cancer survival by socioeconomic indicators and race/ethnicity among elderly women diagnosed with cervical cancer.

METHODS

We studied 1251 women with cervical cancer aged 65 or older, identified between 1992 and 1999 from the Surveillance, Epidemiology, and End Results [SEER]-Medicare linked data. All women had similar access to care through Medicare fee-for-services insurance. A composite measure of socioeconomic status was created using census tract level data for poverty, education, and income. Cox proportional hazard modeling was used for all-cause and cervical cancer-specific survival analysis.

RESULTS

Increased age (P < 0.0001) and advanced tumor stage (<0.0001) were associated with poorer all-cause and cervical cancer-specific survival. After adjustment for age, stage, and treatment, increased co-morbidity scores and having non-squamous cervical cancer were associated with poorer all-cause survival (P < 0.001). After adjusting for confounders, women receiving hysterectomy vs. no surgery or any treatment had significantly better all-cause and cervical cancer-specific survival. Socioeconomic factors were not associated with either all-cause (P for trend = 0.79) or cervical cancer-specific (P for trend = 0.81) survival. No racial/ethnic differences in all-cause or cervical cancer-specific survival were observed after adjusting for socioeconomic factors.

CONCLUSION

Among women with similar access to care, neither minority race/ethnicity nor poorer socioeconomic status were associated with poorer survival in this large sample of older women diagnosed with invasive cervical cancer. Presence of co-morbid conditions and treatment were important predictors of cervical cancer survival.

Risk assessment for cancer surgery in elderly patients

Global growth of the elderly population is requiring healthcare providers to cater for an expanding elderly cancer subpopulation. The aggression with which cancer should be treated in this subpopulation is an ethical dilemma and is an ongoing debate, as surgeons have feared increases in postoperative morbidity and mortality. As a result elderly patients often receive suboptimal cancer treatment. The need for standardization of cancer surgery is well recognized despite the difficulties in view of heterogeneity of the group. In this article, epidemiological changes, tumor biology specific to elderly cancer are visited, operative risk assessment tools are discussed, and interim results of ongoing multinational investigation ie, PACE (Preoperative Assessment of Cancer Elderly) revealed.

Optimising surgical management of elderly cancer patients

BACKGROUND: Elderly population is on rise. It is an ethical dilemma how aggressive one should be when it comes to treat cancer in elderly. Presumed fear of increased postoperative morbidity and mortality has resulted in delivery of sub-optimal cancer surgery. METHODS: In this review article we visit physiology of the aged, tools available to assess surgical risks in oncogeriatric patients, and current practice in the management of common cancers encountered in surgical oncology, with the view of increasing awareness on optimising surgical management of senior patients with cancer. A pubmed search for cancer, surgery, elderly, was carried out. RESULTS: Cancer is on rise with increasing age predominantly affecting breast, gastrointestinal tract and lung. Increasingly more surgeons are offering surgery to elderly cancer patient but selection bias is prevalent. Available data reflect short and long-term outcome of cancer surgery in elderly is not greatly different to that of younger patient. Declining physiological reserve along with inability to respond adequately to physiological stress are salient age related changes. Comprehensive Geriatric Assessment (CGA) is not tested in surgical patient. There is need for a tool to define individualised operative risk. Preoperative assessment of cancer in elderly is designed to offer this information based on functional status of an individual utilising currently available tools of risk assessment. CONCLUSION: All elderly cancer patients should be offered optimal treatment depending on their functional status not on chronological age. Oncogeriatric patient would benefit from dedicated multidisciplinary approach. Recruitment of elderly cancer patients to more clinical trials is needed to enhance our knowledge and to offer optimum treatment to this unique subgroup.

The surgical management of elderly cancer patients

Although cancer in the elderly is extremely common, few health professionals in oncology are familiar with caring for series of oncogeriatric patients. Surgery is at present the first choice, but is frequently delivered suboptimally: under-treatment is justified by concerns about unsustainable toxicity, whilst over-treatment is explained by the lack of knowledge in optimising preoperative risk assessment. This article summarises the point of view of the Surgical Task Force @ SIOG (International Society for Geriatric Oncology), pointing out differences from, and similarities to, the younger cohorts of cancer patients, and highlighting the latest updates and trends specifically related to senior cancer patients.
